Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a synchronization signal (SS) block index associated with a SS block; scramble a physical broadcast channel (PBCH), associated with the SS block, based at least in part on the SS block index; and transmit the SS block including a tertiary synchronization signal (TSS) and the PBCH, wherein the TSS includes information that identifies the SS block index associated with the SS block, and wherein the TSS is frequency division multiplexed with the PBCH in two or more orthogonal frequency-division multiplexed (OFDM) symbols of the SS block. Numerous other aspects are provided.

Abstract: Techniques for signaling dynamic control region for PRACH transmission are described. In an aspect, the disclosure describes a method for receiving, at a user equipment (UE), an indication of a number of control symbols that the UE is to assume when transmitting physical random access channel (PRACH), and transmitting, by the UE, the PRACH over one or more slots based on the number of control symbols. In another aspect, the disclosure describes a method for generating, at a network device, an indication of a number of control symbols that a UE is to assume when transmitting PRACH, transmitting, by the network device, the indication to the UE. A UE and network device configuration as well as apparatuses and computer-readable medium related to these methods are also described.

Abstract: Various aspects relate to flexible mobility for a user equipment (UE) based on supported mobility modes of a network and UE conditions. A network may support one or more of a downlink based mobility mode, an uplink based mobility mode, or a hybrid mobility mode for a connectivity state of a UE. A UE may determine a serving cell based on at least one downlink signal. The UE may determine based on the at least one downlink signal, a set of supported mobility modes for the serving cell, including at least one of a downlink based mobility mode, an uplink based mobility mode, or a hybrid based mobility mode. The UE may follow a mobility procedure based on a selected mobility mode from the determined set of supported mobility modes. Other aspects relate to a base station transmitting synchronization signals to support flexible mobility.

Abstract: Aspects of the present disclosure relate to techniques for transmitting and processing synchronization signals (SS) for different purposes. In some cases, transmitting multiple SS blocks simultaneously using frequency division multiplexing (FDM), and possibly different beams, may allow a UE to reduce a measurement window.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Aspects of the present disclosure provide a two-stage uplink transmission scheme. As described herein, a UE may transmit a first portion of an uplink signal to an AN, receive a first acknowledgment responsive to the first portion, and after receiving the first acknowledgement, transmit the first portion and a second portion of the uplink signal to the AN. The AN may receive a first portion of an uplink signal from UE, transmit a first acknowledgment responsive to the first portion, and after transmitting the acknowledgement, receive the first portion and a second portion of the uplink signal from the UE.

Abstract: The present disclosure relates to signaling information in physical broadcast channel (PBCH) demodulation reference signals (DMRS). In one example, a network entity may transmit the signaling information carried by a DMRS in one or more resource elements of physical broadcast channel (PBCH) symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block. In another example, a user equipment (UE) may receive the signaling information carried by the DMRS within one or more resource elements of PBCH symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block on a broadcast channel from the network entity.
